I am a Senior Research Scholar at the Center for Biomedical Ethics at Stanford University. The heart of my work is aimed at promoting social justice. Drawing on my training in cultural anthropology, science studies, and empirical bioethics, my work is deeply interdisciplinary, and addresses a range of topics challenging entrenched scientific and medical beliefs about gender, sexuality, and the body. My current research, which has been supported by the National Science Foundation, examines “sex testing” of elite female athletes. My work on this topic has appeared in Science, The American Journal of Bioethics and the BMJ as well as The New York Times. I helped to mount Dutee Chand’s successful appeal against the IAAF’s hyperandrogenism regulation at the Court of Arbitration for Sport, and served as an expert witness in the hearing. I began my career looking at controversies over treatment for people with intersex traits, which resulted in my book Fixing Sex: Intersex, Medical Authority, and Lived Experience (Duke 2008). My research has been covered in the New York Times, Time, BuzzFeed, The Week, CNN, ESPN, The Daily Beast, The Los Angeles Times, Boston Globe, Jezebel, Slate, The Advocate, La Liberation, The Chronicle of Higher Education, San Jose Mercury News, and the Toronto Star. I’ve also appeared on The World, BBC, CBS News, NBC News, KCBS, CTV News, Q Radio, Al Jazeera, and the Australian Broadcasting Corporation, among others.
